Struct PciNodeView 

pub struct PciNodeView<'a> { /* private fields */ }

Specialized view for PCI bridge nodes.

Implementations

impl<'a> PciNodeView<'a>

pub fn interrupt_cells(&self) -> u32

Returns the #interrupt-cells property value.

Defaults to 1 for PCI devices if not specified.

pub fn interrupt_map_mask(&self) -> Option<Vec<u32>>

Get the interrupt-map-mask property if present.

pub fn bus_range(&self) -> Option<Range<u32>>

Get the bus range property if present.

pub fn ranges(&self) -> Option<Vec<PciRange>>

Get the ranges property for address translation.

pub fn interrupt_map(&self) -> Result<Vec<PciInterruptMap>, FdtError>

解析 interrupt-map 属性

pub fn child_interrupts( &self, bus: u8, device: u8, function: u8, interrupt_pin: u8, ) -> Result<PciInterruptInfo, FdtError>

获取 PCI 设备的中断信息 参数: bus, device, function, pin (1=INTA, 2=INTB, 3=INTC, 4=INTD)

Methods from Deref<Target = NodeGeneric<'a>>

pub fn id(&self) -> NodeId

pub fn path(&self) -> String

pub fn regs(&self) -> Vec<RegFixed>

pub fn interrupt_parent(&self) -> Option<Phandle>

Returns the effective interrupt-parent, inheriting from ancestors.

pub fn clocks(&self) -> Vec<ClockRef>
